Microsoft 365 Business
Microsoft 365 Business

It’s a great package, but if you’re in a virtual desktop environment, if you need the Phone System in Teams, if you need Windows Defender Advanced Threat Protection, or if you need a full version of Azure Active Directory.. then you need to consider another bundle.

From Microsoft:

Can I add Phone System and Calling Plans to Microsoft 365 Business?

No, Phone System and Calling Plan are reserved for customers who have more advanced needs. Customers who require these capabilities should look at Microsoft 365 Enterprise offerings.

Can Microsoft 365 Business customers use Windows Defender Advanced Threat Protection?

No, those that require Windows Defender Advanced Threat Protection need either Windows 10 Enterprise E5 or Microsoft 365 Enterprise E5.

Can customers create hosted Windows 10 VMs with a Microsoft 365 Business subscription?

No, customers that require virtualization should purchase Windows 10 Enterprise or a Microsoft 365 Enterprise subscription.

Does Azure Active Directory Premium P1 come with Microsoft 365 Business?

Microsoft 365 Business is built on technology from across Microsoft and while it shares some features with Azure Active Directory, it is not a full version. The security and management policies created in Microsoft 365 Business rely on some Azure functionality but does not include all features (e.g. self-service features, conditional access features, and reporting). Customers may choose to purchase Azure Active Directory Premium P1 or P2 as an add-on to Microsoft 365 Business
